GAS-BURNER FOR HEATING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 401,445, dated April 16, 1889.

Application filed August 7, 1888.

To all whom it may concern:

Be it known that I, PHILLIP Lnssnn, of Ridgway, in the county of Elk and State of Pennsylvania, have invented a new and Improved GasBurner for Heating Purposes, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a broken plan view of mynew burner. Fig. 2 is a longitudinal sectional ele vation of the same on line as roof Fig. 1. Fig. 3 is a transverse sectional view on line 3 y of Fig. 1. Fig. 4. is a longitudinal sectional elevation showing a modification, and Fig. 5 is a transverse sectional view of the same on the line 2 z of Fig. a. y

The invention will first be described in connection with the drawings, and then pointed out in the claims.

, A represents a casting, formed with a central elevated plat-form, a, outer surrounding flanges or walls, I) f, narrow floor b, and innor walls, b which support the elevated platform aabove the floor b. The walls 1) fl) and the floor 6 form a narrow channel or chamber, B, surrounding the whole interior of the burner. The upper surface of the elevated platform a is on the same level as the upper edges of the outer walls, 5 f, and upon them -is bolted the cap-plate 0, formed with side walls, 0 0, end walls,.c c, and top wall, 0 forming chamber D. At its longitudinal edges the cap-plate O is formed with the side flanges, O 0, which cover the channel B, as shown clearly in Fig. 3, and which are perforated with numerous holes 8 e, through which the gas escapes from the channel B and from which it is burned. The flame is therefore each side of the elevated chamber D. The gas is admitted to this chamber above the elevated platform a through an opening, a, in said platform, in which a gas-pipe may be fitted. The gas becomes heated in the Serial No. 282,173. (No model.)

chamber D and expanded and mixed with air (see Figs. 2 and 3 of the drawings) and enters the surrounding channel 13 at cl (1 at the ends of the chamber D, the walls 0 0 matching with the walls ff of the lower casting, A, to form the said passages (Z for that purpose. In this heated and expanded state the gas issues from the perforations e 6 along the sides and is burned, producing intense heat.

In Figs. 4 and 5 the gas enters the top chamber, D, through apipe, M, at one end of the said chamber. The gas passes the whole length of the chamber D and descends to the channel B through passage d, from whence it rises through the perforations e e and is burned.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The gas-burner herein shown and described, constructed to form a top chamber to which the gas is first applied, an end passage leading from said top chamber downward, and side chambers or channels on a lower level than the top chamber and communicating therewith through said end passage, said side chambers being covered by perforated plates, substantially as described.

2. A gas-burner consisting in the raised bottom (1, having a surrounding channel, B, around its sides and ends, the top of the channel being open, and the raised bottomless capplate 0, resting at its lower longitudinal edges on the side edges of the bottomo, and with its end walls, 0, on the outer end walls, f f, of the chamber B to form the end passages, d d, and formed with the perforated side plates, 0 C, forming covers for the side of the channel B, the chamber D, formed by said cap-plate, being provided with a gas-inlet, substantially as set forth.

PHILLIP LESSER.
